Embedded system is a combination of both hardware and software, the testing and development of which calls also for other things than just software and the device itself. It is often necessary to measure the signals of the device, simulate the input signals or otherwise control the device from the outside during its testing. Without an appropriate testing environment, testing a device becomes slow, laborious and unreliable.
Any machine including rotating or moving parts will break down sooner or later - unless it is properly serviced. Uninterrupted functioning is traditionally maintained applying predictive maintenance. That is a way to ensure that the device functions flawlessly until its next scheduled servicing.
Software development relies on agile practices and methods, which avoid large debacles and promote teamwork. Testing is an inseparable part of the development process right from the definition phase. The tasks overlap and information moves smoothly within a modern design team. The test engineer is a team member and no longer considered a messenger of bad news.
Toroidion electric car’s release in Monaco 2015 attracted huge international attention. Its promised power of 1 megawatt, or over 1 300 hp, ferocious acceleration and operational range of 500 km left the experts' jaws open. The father of the car idea, Pasi Pennanen, has made a long career in design tasks with cars like the Formulas, Jaguar, Aston Martin and Honda. Pennanen needed experienced experts for every component to design the technology of the car.
“IoT platform” can mean many different things. It usually refers to an IoT application platform, in other words a software platform that collects data from various sensors and IoT devices. The collected data can then be analyzed and used in various applications. Such platforms are usually in the cloud.
In principle, all products and systems must be safe, in other words, they can't have any unacceptable risk factors. But some risks always remain – no product is 100% safe.
Alternating current (AC) motors have over a century of history. During the last decades, they have dominated the market for motor drives used in industrial and consumer applications. But in the case of variable speed drives, there were some areas where DC motors were the only option for quite long, especially when torque control or a high dynamic control was required. This is now changing as the availability of compact and effective hardware solutions lets vector control expand to cost-sensitive areas like home appliances and consumer electronics.
